PROBLEM TO BE SOLVED: To appropriately spray pesticide in both times when planting a seedling mat for high-density raising seedlings and planting seedling mat for standard-type raising seedlings.SOLUTION: A transplanter 1 includes: a seedling planting device 23 that forks up seedlings, with planting pawls 30, from a seedling mat placed on a seedling tray 29 and plants them in a field； and a pesticide spray machine 400 for spraying pesticide. The transplanter is configured to change a pesticide spray amount of the pesticide spray machine 400 according to whether planting a seedling mat for high-density raising seedlings or a seedling mat for standard-type raising seedlings in which the seedlings are grown at a density lower than the seedling mat for the high-density raising seedlings.SELECTED DRAWING: Figure 37【課題】高密度育苗の苗マットの植付時と、標準型育苗の苗マットの植付時の両方で、薬剤散布を適切に行う。【解決手段】田植機１は、苗載台２９に載置された苗マットから植付爪３０で苗を掻き取って圃場へ植え付ける苗植付装置２３と、薬剤を散布する薬剤散布機４００を備え、高密度育苗の苗マットの植付時と、高密度育苗の苗マットよりも苗が低密度に生育された標準型育苗の苗マットの植付時とで、薬剤散布機４００の薬剤散布量を変更するように構成している。【選択図】図３７
